In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

Referring to fig. 1, fig. 1 is a first flowchart of a data uplink method according to an embodiment of the present application. As shown in fig. 1, a data uplink method includes the following steps:

step 101, acquiring multi-signature information of N participants.

N is an integer greater than or equal to 2.

In the embodiment of the application, transactions participated in by a plurality of participants randomly occur among N participants. When a transaction is conducted between the N participants, the transaction can be conducted between part of the N participants, or all the N participants can participate in the incoming transaction.

Therefore, it is necessary to acquire multi-signature information of N participants. And verifying the multiple batches of transactions participated in by a random participant in the N participants in the subsequent process by borrowing a multiple signature technology based on the multiple signature information, thereby realizing the verification of the transaction data during the data uplink.

The multi-signature information specifically includes multiple signatures formed on the basis of private keys of different parties.

The private keys of the N participants can be acquired when transaction requests of the N participants for conference resolution voting are received, and generation of multi-signature information is achieved.

And 102, sending a first calling request of the intelligent contract on the chain to a block link point based on the multi-signature information.

The first call request carries the multi-signature information.

And calling the intelligent contract on the chain through the first calling request so as to upload the multi-signature information to the block chain and realize signature checking processing during uplink of batch transaction data between the subsequent N participants.

Where an intelligent contract often refers to a piece of code running on a blockchain network.

When a first call request of an intelligent contract on a chain is sent to a block link point based on multi-signature information, the multi-signature information can be packaged into a corresponding first call request after one transaction, the multi-signature information is entered into the intelligent contract on the chain, the intelligent contract on the chain is called and executed to realize the verification processing of the uplink transaction of the multi-signature information, after the processing is finished, each node on the block chain is triggered to carry out common identification, the multi-signature information is blocked after the common identification, and the conclusion is obtained, so that the subsequent centralized uplink processing process of the batch transaction under the chain and the batch transaction can be started.

103, after obtaining the signature uplink feedback information fed back by the block link point based on the first call request, obtaining a plurality of to-be-uplink transaction information generated by different participant combinations among the N participants and an execution dependency relationship among the to-be-uplink transaction information;

after the first call request is responded to the multi-signature information to complete the uplink, the signature uplink feedback information of the block chain node is obtained, and at the moment, the downlink program can perform downlink logic processing to obtain a plurality of pieces of to-be-uplink transaction information generated by different participant combinations in the N participants and execution dependency relationships among the to-be-uplink transaction information.

Wherein, different transaction information to be linked up is generated in a participant combination formed by a plurality of participants in the N participants.

Different groups of participants may contain the same member of the participant, and different groups of participants may contain members of different participants, but the transactions performed by different groups of participants are different transactions. And there may be some dependency between the batch transactions that selected ones of the N participants participate in, or all of the participants participate in.

The information of the transaction to be linked includes transaction result, transaction processing procedure, signature of each participant in the transaction, etc.

Specific transactions are for example transfers, votes, etc.

In the process, calculation and account transfer can be carried out for any time by aiming at a calculation part under a transaction chain in a multi-signature mode, multiple signatures are used as signature verification marks after the calculation process is finally finished, batch transaction data under the line are verified on the chain through intelligent combination on the chain, transaction changes under the chain are finally executed on the chain, and final chain-winding processing of transaction information to be subjected to chain winding is realized.

And 104, sending a second call request of the intelligent contract on the chain to the blockchain node based on the transaction information to be linked and the execution dependency relationship.

And the second calling request is used for verifying the transaction information to be linked according to the multi-signature information and the execution dependency relationship after the intelligent contract on the link is executed, and linking the transaction after the verification is correct.

When a second calling request is sent to the block chain node, a plurality of to-be-uplink transaction information and execution dependency relationships generated by different participant combinations in the N participants are packaged and embedded into the calling request, one-time uplink verification processing of batch transaction information is provided, and the frequency of calling intelligent contracts on chains and the frequency of transaction data verification and block entering operation performed by using the intelligent contracts on chains are reduced.

The method comprises the steps of reporting multi-signature information of N participants to a block chain through primary on-chain intelligent contract calling before batch transaction, calling the on-chain intelligent contract again after the batch transaction chain is processed, enabling the on-chain intelligent contract to use the multi-signature information of the N participants who have been linked to carry out signature verification processing on transaction information to be linked up corresponding to the batch transaction, achieving verification of the transaction information to be linked up, carrying out uplink processing on the transaction information after the transaction information is verified to be correct, improving processing efficiency of uplink data process under the scene that a large amount of transaction data are frequently generated, meeting requirements of batch data and achieving expansion of application scenes of the block chain.

In the embodiment of the application, the intelligent contract on the chain is called by acquiring the multi-signature information of N participants, after the uplink of the multi-signature information is ensured, acquiring a plurality of to-be-uplink transaction information and execution dependency relationships among the to-be-uplink transaction information respectively generated by different participant combinations in the N participants, the chain intelligent contract is called again, the chain intelligent contract is verified according to the multi-signature information and the execution dependency relationship after being executed, the transaction chain is carried out after the verification is correct, the process reduces frequent calling of the intelligent contracts on the chain, frequent verification of transaction data and blocking operation times by using the intelligent contracts on the chain, improves the processing efficiency of a data chain winding process under the scene of frequently generating a large amount of transaction data, meets the chain winding requirement of batch data, and realizes the expansion of a block chain application scene.

In the embodiments of the present application, different embodiments of a data uplink method are also provided.

Referring to fig. 2, fig. 2 is a second flowchart of a data uplink method according to an embodiment of the present application. As shown in fig. 2, a data uplink method includes the following steps:

step 201, acquiring multiple signature information of N participants.

Wherein N is an integer greater than or equal to 2;

the implementation process of this step is the same as that of step 101 in the foregoing embodiment, and is not described here again.

And 202, sending a first call request of the intelligent contract on the chain to a block link point based on the multi-signature information.

The implementation process of this step is the same as that of step 102 in the foregoing embodiment, and is not described here again.

Step 203, after signature uplink feedback information fed back by the block link point based on the first call request is obtained, obtaining transaction information respectively generated by different participant combinations in the N participants;

such as the amount of money transferred, the transfer originator, the transfer recipient, the transfer time, transaction details to which the transfer is subject, etc., to which the transfer transaction relates, or such as the voter, the choice in the vote, the voting time, the details to which the vote is subject, etc., to which the vote relates.

Step 204, respectively acquiring signature information of each participant contained in each participant combination;

step 205, performing signature processing on the transaction information based on the signature information to obtain the to-be-uplink transaction information generated by each of the participant combinations, and determining an execution dependency relationship between the transaction information as an execution dependency relationship between the to-be-uplink transaction information.

In order to ensure that the uplink verification mechanism is adapted when the downlink transaction is linked up, in the embodiment of the present application, signature processing needs to be performed on the transaction information respectively generated by each participant combination, so as to ensure that information marking is performed on each transaction information and verification information is provided for verification processing during subsequent uplink transaction.

This process also implements an under-chain attestation mechanism for batch transaction processing, avoiding the possibility of under-chain computation doing malicious at a lesser cost.

Step 206, based on the to-be-linked transaction information and the execution dependency relationship, sending a second call request of the intelligent contract on the link to the blockchain node.

The implementation process of this step is the same as that of step 104 in the foregoing embodiment, and is not described here again.

Further, in an optional implementation manner, in step 203, obtaining transaction information generated by different participant combinations in the N participants respectively includes:

when the transaction is triggered by different participant combinations in the N participants, recording the processing process of the transaction to obtain a transaction record and a transaction state corresponding to the transaction record;

and for each participant combination, obtaining the transaction information containing the corresponding transaction record and the transaction state respectively.

The transaction record is a record of transaction processing actions and corresponding transaction processing information occurring in the transaction processing process, and the acquisition of the transaction record may be to record the transaction processing actions and the transaction processing information occurring in a certain time length according to the time length, or to record one transaction processing action and one transaction processing information for each transaction processing step according to a specific transaction processing item.

The transaction state corresponding to the transaction record is that each transaction record corresponds to a transaction state, and the transaction state indicates the transaction processing state at the transaction time point after the transaction processing action corresponding to one transaction record occurs, for example, after the transaction processing action, the current balance of both parties of the transfer transaction is what, after the voting transaction, the current vote number of each voting option is what, and the like.

The transaction records form a state certificate of the corresponding transaction state, and the correctness of the transaction state can be verified through the transaction records.

Correspondingly, the step 206 of sending a second invocation request of the intelligent contract on the chain to the blockchain node based on the information of the transaction to be linked and the execution dependency relationship includes:

packaging the plurality of to-be-uplink transaction information and the execution dependency relationship among the to-be-uplink transaction information to obtain to-be-uplink transaction data packets;

and sending a second call request of the intelligent contract on the chain carrying the transaction data packet to be linked to the block chain node.

When a second call request for the intelligent contract on the chain is sent to the block chain link point, all transaction information to be linked generated in the batch transaction process needs to be packaged and then entered into the participating network.

At this time, when the transaction information in the to-be-uplink transaction information includes the transaction record and the transaction state, after the second call request carrying the to-be-uplink transaction data packet is sent to the block chain node, after the called on-chain intelligent contract is executed, the transaction state in the to-be-uplink transaction information needs to be verified by combining the multi-signature information, the execution dependency relationship among the to-be-uplink transaction information and the transaction record, and the transaction uplink transaction is performed after the transaction state is verified to be correct.

That is, at this time, the second invocation request is used for verifying the transaction state in the transaction information to be linked according to the multi-signature information, the execution dependency relationship and the transaction record after the intelligent contract on the link is executed, and performing the transaction linking after the verification is correct.

In the process, for the problem of dispute and dispute possibly existing in the calculation process of the downlink transaction, a set of downlink-uplink interaction mode is designed to carry out downlink record and uplink verification judgment and uplink execution of transaction data by introducing a downlink transaction state S, a transaction record SP and a downlink calculation condition execution dependency relation C (which can be realized by a directed acyclic graph).

The concept of S is similar to the concept of world state on the chain, and changes instantly with the execution of the trade action under the chain, and is the trade state under the chain after the accumulation of the execution action under the chain.

The execution dependency relationship is information such as an expiration time and a duration time of a certain transaction, a start time of another transaction having a dependency relationship with a sequence of execution order with the transaction, and the like, and when the intelligent contract on the chain is called to perform transaction chaining, the intelligent contract on the chain is executed and then whether a time conflict exists between the transactions is checked, for example, whether a certain voting result is selected before a block number n (n is used as an entry parameter, and the voting result is used as an execution result) is checked through the execution dependency relationship, so that verification of the transaction information to be chained is realized.

In an alternative embodiment, after acquiring the signed uplink feedback information fed back by the block link point based on the first call request, the step 203 acquires the transaction information generated by different combinations of the N participants, including:

after signature uplink feedback information fed back by the block link point based on the first call request is obtained, a temporary interaction space is opened up;

and acquiring transaction information generated by different participants in the N participants based on the temporary interaction space.

The temporary interaction space is used for different participants in the N participants to combine and execute the transaction, and provides service resources required by execution for the triggered transaction.

When the temporary interaction space is opened up, resources occupied by the procedure under the chain are prepared for N participants to execute batch transaction, and the execution of a large amount of frequently generated transaction data under the chain is ensured.

In the process, for the part of the transaction under the chain, a temporary interaction space is opened for multiple parties interacting under the chain in a multi-signature mode, calculation and transfer can be carried out for any time in the interaction space, the multiple signatures are used as marks to calculate the final change of the world state on the chain after the calculation process is finally finished, and finally the transaction data and the state change under the chain are executed on the chain through an intelligent contract on the chain to realize the data chaining.

Correspondingly, after sending the second invocation request of the intelligent contract on the chain to the blockchain node based on the information of the transaction to be linked and the execution dependency relationship, the method further includes:

and after acquiring the uplink transaction feedback information fed back by the block link point based on the second call request, closing the temporary interaction space.

After acquiring the transaction uplink feedback information fed back by the blockchain node based on the second call request and determining that the batch transaction data is successfully uplink, releasing the resources occupied by the downlink program, closing the temporary interactive space and realizing the interactive space life cycle management.
